Siri dictation repeats the words I'm saying

When I dictate a text or words, the Siri receiver repeats in some way each captured word when I want to write in a UITextView, my UITextView is implemented as simple as possible:

Code Block
#pragma mark - UITextViewDelegate
- (BOOL) textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
return YES;
}
- (void)textViewDidChange:(UITextView *)textView
{
//  NSLog(@"-> textViewDidChange: %@", textView.text);
  if (textView == self.txtViewItem)
  {
    if ([self sameCharsInString:textView.text])
    {
      NSString *firstChar = [textView.text substringWithRange:NSMakeRange(0, 1)];
      textView.text = firstChar;
    }
    if (textView.text.length > 1)
    {
      NSString * character = [textView.text substringWithRange:NSMakeRange(1, 1)];
      textView.text = [textView.text stringByReplacingCharactersInRange:NSMakeRange(1, 1) withString:[character lowercaseString]];
    }
  }
}
-(BOOL)sameCharsInString:(NSString *)str{
  if ([str length] == 0 ) return NO;
  return [[str stringByReplacingOccurrencesOfString:[str substringToIndex:1] withString:@""] length] == 0 ? YES : NO;
}



So how can I detect if Siri Dictation was used for the UITextView,
Please any help?
I think you need to adjust your device settings related Siri, Voice Over, dictation, and etc.
